    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 H[U*' 2TJ  
    -ZJ:<  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: CKgyv%T5m:  
    enableservice('AutomationServer', true) B`Pi\1H6%  
    enableservice('AutomationServer') {.W%m  
    UQr+\ u  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 1-<Xi-=^{t  
    Rv o<ISp  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: VQ`O;n6/`  
    1. 在FRED脚本编辑界面找到参考. oaE3Aa  
    2. 找到Matlab Automation Server Type Library !{\c`Z<#  
    3. 将名字改为MLAPP U {v_0\ES

    L}nc'smvM  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 6, ~aV

    现在将脚本代码公布如下,此脚本执行如下几个步骤: $!lxVZ>  
    1. 创建Matlab服务器。 huE#VY /t  
    2. 移动探测面对于前一聚焦面的位置。 uqH ;1T;s  
    3. 在探测面追迹光线 {D8 IA3w  
    4. 在探测面计算照度 .=S{  
    5. 使用PutWorkspaceData发送照度数据到Matlab -B!pg7>'##  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 l71\II  
    7. 用Matlab画出照度数据 u:|5jF  
    8. 在Matlab计算照度平均值 CJ b ~~  
    9. 返回数据到FRED中 = %m/
